Several cross country/athletic shoes available on wiggle.com.au. Purchased two of the Speedcross 4 Salomons for myself - perfect for trail running, IPSC and cross country.
Use the side guide, it's 100% accurate.
37% off (or there abouts) stacked with NEWAU discount code for additional $20 off.
Salomons fit quite narrowly, so consider the wider model if you are that way inclined.
Please be mindful that they are designed with extra long grips on the sole. You may wish to have a look at other clearance protects listed on their website.
The one you linked are AU$149.58, so minus $20 would be $129.58.
edit: I see, black are AU$139.87 - $20.
